The primary components of a bio-data are likely universal. They include the following items:
However, BEWARE for those of you reading this who are IN THE UNITED STATES. The term "Curriculum Vitae" does NOT operate interchangeably with "résumé". It is, here in the U.S., a specialized format of a résumé, specifically for use in scientific or academic fields (teachers and scientists). Outside the US, however, the two terms are more synonymous.
It's probably best to consider using either a CV or a résumé rather than a full-blow bio-data for job searching. In addition to many samples from the Internet to help get you going, there are services from such places as CareerBuilder.com and Monster.com that will write your CV/résumé for you.
If you're interested in building your own, you can probably find everything you need at this site, which is dedicated to CV writing.
Here's a no-nonsense guide to a CV, including definitions and pointers. And for a much more detailed guide, and a nice, clean PDF sample (NOT to be used as a template, however, as the site expresses), try this page, from the University of Texas at Austin. It gives a columned list of what to include in a CV and what the differences are between a CV and a résumé.
There are, literally, thousands of examples of bio-data documents available on the Internet. Some of them are not as professional as others. One of the best ones I've seen is this one, and I'm tempted to use it myself.
But, if you are more in need of guidance in building a bio-data document, this article should shed much light on what and why of the document itself.
Do a search for "bio-data samples", or "biodata samples" in Google to find so many templates you'll have a hard time deciding which one to use.
In the end, be careful what you do and do not include on your bio-data. You will be surprised how much weight the résumé, CV or bio-data can carry, and it can either open doors for you, or shut them forever.
Good luck, and I hope this article has helped you some.
